like Malloc, Realloc and especially Free conflict with already existing names
on some operating systems or other packages.  That is reason enough to change
the names of the OpenSSL memory allocation macros to something that has a
better chance of being unique, like prepending them with OPENSSL_.

This change includes all the name changes needed throughout all C files.

"Jan Mikkelsen" <janm@transactionsite.com> correctly states that the
OpenSSL header files have #include's and extern "C"'s in an incorrect
order.  Thusly fixed.

initialised, at which point an appropriate default was chosen. This meant a
call to RSA_get_default_method might have returned FALSE.

This change fixes that; now any called to RSA_new(), RSA_new_method(NULL), or
RSA_get_default_method() will ensure that a default is chosen if it wasn't
already.

the BN_CTX implementation could now easily be changed.

same as RAND_seed() but takes an estimate of the entropy as an additional
argument.

Primes p where (p-1)/2 is prime too are called "safe", not "strong".

and verify rather than direct encrypt/decrypt.

OpenSSL is compiled with NO_RSA, no RSA operations can be used: including
key generation storage and display of RSA keys. Since these operations are
not covered by the RSA patent (my understanding is it only covers encrypt,
decrypt, sign and verify) they can be included: this is an often requested
feature, attempts to use the patented operations return an error code.

This is enabled by setting RSA_NULL. This means that if a particular application
has its own legal US RSA implementation then it can use that instead by setting
it as the default RSA method.

Still experimental and needs some fiddling of the other libraries so they have
some options that don't attempt to use RSA if it isn't allowed.

in cryptlib.h (which is often included as "../cryptlib.h"), then the
question remains relative to which directory this is to be interpreted.
gcc went one further directory up, as intended; but makedepend thinks
differently, and so probably do some C compilers.  So the ../ must go away;
thus e_os.h goes back into include/openssl (but I now use
#include "openssl/e_os.h" instead of <openssl/e_os.h> to make the point) --
and we have another huge bunch of dependency changes.  Argh.

There were problems with putting e_os.h just into the top directory,
because the test programs are compiled within test/ in the "standard"
case in in their original directories in the makefile.one case;
and in the latter symlinks may not be available.
